A network administrator wants to implement an authentication process for temporary access to an organization's network.
Which of the following technologies would facilitate this process?

  1. Captive portal
  2. Enterprise authentication
  3. Ad hoc network
  4. WPA3

Answer(s): A

A captive portal forces users to authenticate or acknowledge usage terms before accessing the network. It is ideal for temporary or guest access.



A user is unable to navigate to a website because the provided URL is not resolving to the correct IP address. Other users are able to navigate to the intended website without issue.
Which of the following is most likely causing this issue?

  1. Hosts file
  2. Self-signed certificate
  3. Nameserver record
  4. IP helper

Explanation:

A user’s local hosts file can override DNS and cause incorrect IP resolution. Since only one user is affected, this is the most likely cause.



A network administrator is planning to host a company application in the cloud, making the application available for all internal and third-party users.
Which of the following concepts describes this arrangement?

  1. Multitenancy
  2. VPC
  3. NFV

  1. Crash cart
  2. Jump box
  3. Secure Shell
  4. Out-of-band management

If an appliance fails to boot, in-band access like SSH is unavailable. Out-of-band management (console server, management port, or modem) allows remote access even when normal network functions are down.



Which of the following attacks utilizes a network packet that contains multiple network tags?

  1. MAC flooding
  2. VLAN hopping
  3. DNS spoofing
  4. ARP poisoning
